AD Leonis
AD Leonis (Gliese 388) is a red dwarf star. It is located relatively close to the Sol system, at a distance of about 16 light years. AD Leonis is a main sequence star with a spectral classification of M3.5V.
Properties
AD Leonis is an active flare star. This star has been classified as spectral type M3.5eV. The projected rotation of this star is only 3 km/s. It is considered a member of the young disk population.
AD Leonis is one of the most active flare stars known, and the emissions from the flares have been detected across the electromagnetic spectrum as high as the X-ray band. The net magnetic flux at the surface is about 3 kG. Besides star spots, about 73% of the surface is covered by active regions.
The star has no known planetary companions.
This star is orbiting through the Milky Way galaxy with an eccentricity of 0.028. This carries the star as close as 8.442 kpc from the galactic core, and as far as 8.926 kpc. The orbital inclination carries it as far as 0.121 kpc from the plane of the galaxy.
The mean value of its surface magnetic field in the star spots is on the order of 103 G (0.1 T) with area coverage above 70% (i.e., well above the typical solar spot coverage).
